Oversized Beer Can from Birra di Sicilia (Messina) dal 1923

I live in Italy and share time between here and Florida. The other day we were cleaning out one of our out-buildings to make way for construction and I came across this over-sized Birra di Sicilia (Messina) dal 1923 can/keg just sitting in a back corner.

I checked the measurements of the can/keg (approx 11 1/2" across the top and 18" tall) with those computations in hand did some quick math (~1837 cubic inches) and determined that the can held ~30 liters of beer.

Confirmed with a few locals that they recall these having beer in them and were distributed this way. I have yet to hear from the Beer Collectors out there that have ever seen another example of this can.

I have looked everywhere and cannot seem to locate a single image of a can this large.

Please help. Thanks. Please contact me if you have ever seen another item like this
